eliminating "mounted filesystem" messages from syslog

linux-howto

http://www.unix.com – Hello all, perhaps this is an odd request, but I have the requirement none the less. Every time I mount a filesystem (at least an ext4 filesystem), I get a line indicating such in the syslog: Oct 9 22:26:28 sulaco kernel: EXT4-fs (dm-1): mounted filesystem with ordered data mode. Opts: I would like to not have these in the syslog. This is an encrypted filesystem that I would like to have no indication whatsoever that it exists. The OS lives on a regular non-encrypted volume. Obviously, messages in syslog indicating a mount of a Device Mapper (dm-1) filesystem will give away the existen (HowTos)

root fs error on boot 38 weeks 3 days ago

When I boot, I always get these messages:

Code: [    5.916703] EXT4-fs warning (device dm-1): ext4_clear_journal_err:4401: Filesystem error recorded from previous mount: IO failure [    5.916775] EXT4-fs warning (device dm-1): ext4_clear_journal_err:4402: Marking fs in need of filesystem check.

This is how / should be mounted

mount /dev/md0 on / type ext3 (rw,errors=remount-ro)

but in fact, it is mounted read-only because of unknown reason so far for me.

cat /proc/mounts /dev/md0 / ext3 ro,relatime,errors=remount-ro,data=ordered 0 0

:/var/log# echo aaa > /tmp/ddd bash: /tmp/ddd: Read-only file system

As ext3 has errors=remount-ro flag, the possible reason is that the filesystem

I'm trying to do the same of this question (multiple linux installation on same filesystem) but I get this result (root filesystem mounted as read-only) . I'm using debian/sid, have successfully modified the initrd /init script and patched the busybox switch_root to chroot into a subdirectory, the filesystem is ext4. The kernel boot but the filesystem is mounted read-only and any variant of mount

Yet another filesystem question. I wanted to use a USB drive that I hadn't mounted for a month or so and was surprised by the fact Ubuntu was unable to mount it. I looked it up in the disk utility and it said it discovered a device with 17 MB instead of 2 GB.

I am in progress of resizing a LUKS encrypted partition that contains a single ext4 filesystem (no LVM or something). The cryptsetup FAQ recommends to remove the old partition and recreate it, but that sounds like wasting a lot time. Therefore I want to proceeed by manually, carefully resizing the partition.

So far, I think that I need to do:

Unmount the existing ext4 filesystem (e.g.

I have a 2TB Western external HDD. Its original filesystem was NTFS but I formatted it to EXT4. I had no problem in Linux; But today after I mounted it using ext2fsd in a windows box, I cant mount it in linux anymore! The drive had no partition but after that windows mount Disk Utility Shows it has a 1KB partition and 2TB unallocated space!!! My Data are not corrupted (I still can view my files us

Hi, when i first installed ubuntu(dual boot win 7), i partitioned it to /boot / and /home. After installing ubuntu for a few months, one of my filesystem /dev/sda7 which is mounted on / is running out of space.

hi everybody,

I have an error when trying to mount my LaCie network kdisque at boot.

it seems to me that mount is coming too early during the boot process when network is not established. see extract from /var/log/messages.

Hello!

I am in a weird problem of not able to set quota on an ext4 file system. I have setup a logical volume on which this ext4 filesystem resides. It's going to be used by an application for dumping data. But we want to setup quota so that it does not consume all the free space of the lv. The application will generate an error log if the quota limit is crossed.
